If you are joining a standalone vCenter Server system to a Linked Mode group, the domain name of the system must match the machine name. If you change either name to make them match, you must also configure the vCenter Server URLs to make them compatible with the new domain name and machine name.

If you do not update the URLs, remote instances of vCenter Server cannot reach the vCenter Server system, because the default vCenter Server URL entries are no longer accurate. The vCenter Server installer configures default URL entries as follows:

■

For the VirtualCenter.VimApiUrl key, the default value is http(s)://<FQDN of VC machine>/sdk.

■

For the Virtualcenter.VimWebServicesUrl key, the default value is https://<FQDN of VC machine>:<installed-webservices-port>/vws.

Procedure

1

From the vSphere Client, connect directly to the vCenter Server instance on which you have changed the domain or host name.
